Just find a converter in google and do it yourself. Not trying to be a jerk, I'm just saying it's not that hard to do.

Shocker_Monkey answered correctly , my question was just about the bottle, and to be honest i tried to convert the weight and I have no clue on how to convert 2lbs 10 3/4 oz in grams, for example 2lbs 10 3/4 oz= how many lbs? my goal is to compare this bottle to my stako.

What is the length of the 77/4500 without the reg in centimeter please? and is weight in grams please?

Thanks a lot

Bottle is 11.5"
Reg is 2 1/8" from the top of the neck of the bottle to the top of the regulator
Using an online converter, I'm coming up with about 26.4 centimeters. Could someone check my math and verify?

For weight, I'm coming up with about 1212 grams total for a 77cu/4500psi with Ultralite regulator.

rob, can you explain why the gloss black tank is about 2oz heavier compared to the others?

I'm guessing that the gel coating is either thicker or heavier than the matte Ninja Dura finish, giving it more weight. This is pure speculation though. Since we do not manufacture the bottles, I'm not 100% sure why it would weigh more...but those are my guesses.
